Benefits of technology

[0064] This system enables the user to incrementally upgrade the performance of the printer by obtaining and paying for appropriate passwords.

Problems solved by technology

This is usually because the cost to the manufacturer of providing the better performance is greater than the cost of providing the lower performance.
This reciprocating motion generally places limits on the speed of printing or copying.
The speed of printing is then limited by factors such as speed of paper feed, the speed of the printer's electronics and the speed of the printhead itself.

Embodiment Construction

[0033] Referring to FIGS. 1 and 2 there are shown the major components of a typical ink jet printer 100. Typically an ink jet printer 100 has a power supply 102, a data input bus 104, an image processor 106, a print engine controller 108, a paper feed mechanism 110, a printhead 112 and an ink cartridge 114. The power supply 102 may be internal or external of the printer 100 and the printhead 112 and ink cartridge 114 may be separate units or combined in a single unit.

[0034] The performance of an ink jet printer is limited by a number of factors, including: [0035] 1) Image processor speed; [0036] 2) Data input bus speed; [0037] 3) Print engine controller speed; [0038] 4) Power supply; [0039] 5) Paper feed mechanism speed; [0040] 6) Printhead speed.

[0041] The printhead firing speed in turn is limited by: [0042] 1) Power consumption; [0043] 2) Heat dissipation; [0044] 3) Ink nozzle refill time; [0045] 4) Heat capacity of ink used.

[0046] The ink nozzle refill time is in turn limited ...

Abstract

A print media cartridge includes a roll of print media comprising an elongate and tubular core. A length of print media is wound upon the core. A power supply is located within the core. The power supply may include a pair of elongate batteries arranged end to end within the core. A housing is provided in which the roll of print media is housed. The housing may include a pair of electrical contact assemblies which are located at opposite ends of the housing.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] The present application is Continuation application of U.S. patent application Ser. No. 10 / 503,888 filed Aug. 9, 2004, which is a 371 of PCT / AU03 / 00155 filed on Feb. 12, 2003 all of which are herein incorporated by reference.FILED OF INVENTION [0002] The present invention relates to devices having replaceable components and is particularly relevant to printing machines and photocopiers. BACKGROUND OF THE INVENTION [0003] With many products the price to the consumer is linked to its performance. For example a printer having a low resolution or print speed generally costs less to buy than a printer having a high resolution. This is usually because the cost to the manufacturer of providing the better performance is greater than the cost of providing the lower performance. For example, a high resolution ink jet printer may have more nozzles in the printhead or more accurate control compared to a low resolution device; a high resolution las...
